Benefits of technology

The present invention is about a washing method that uses electrolyzed water to achieve the best washing results, without the need for detergent. This washing method allows users to add a reduced amount of detergent or not at all. Additionally, an auxiliary device of the washing machine is provided that is simple in structure and easy to install, without changing the internal structure of the current washing machine. The invention also adjusts the pH value of the washing liquid to between 9 and 11, which results in excellent washing without detergent, reducing expenses and avoiding environmental pollution. The structure of the invention is simple, and the operations, such as assembly, maintenance, and disassembly, are easy to cope with. The invention increments the functions of the existing washing machine, making it highly adaptable and cost-effective.

Problems solved by technology

However, under the washing conditions of the present invention, this influence hardly exists, so we infer that the hardness of water will not have any practical negative effect on detergency.

example 1

[0083]The water temperature is predetermined at 10° C. and capacity of 100%, washing operation is performed by employing active electrolyzed water under standard course: During the process of washing: under actual water temperature of 9.2° C., the tap water flows into the electrolyzing cell, from which alkaline ionized water and acidic ionized water with steady PH are produced, the former will be used to regulate water quality by adding modifying agent and then enter into the washing tub after being activated, while the latter will be drained. PH in the tub at this moment reaches 10.57, which is the best value for washing, meanwhile, normal washing will begin when the alkaline ionized water inflow reaches the predetermined water level and terminate after conducting the standard course for fifteen minutes at least. The surface tension is 31 mN / m, electrical conductivity is 261 us / cm and detergency ratio is 0.2258. The activated alkaline ionized water with steady PH performs the same ...

[0084]The water temperature is predetermined at 10° C. and capacity of 60%, washing operation is performed by employing electrolyzed water under standard course:

[0085]Group 1, During washing under water temperature of 11.5° C., tap water is firstly electrolyzed in the electrolyzing cell in which alkaline ionized water and acidic ionized water with steady PH will be generated, the alkaline ionized water flows into the washing tub while the acidic ionized water will be stored. By adding certain dose of modifying agent, PH in the tub will be 10.405 that suitable for washing. After the alkaline ionized water is introduced to the set water level, washing is carried out for eight minutes, it is measured that the surface tension is 34 mN / m, electrical conductivity is 486 us / cm and detergency ratio is 0.2015. It can be concluded from the experiment data in this group that: the electrical conductivity is relatively high. Furthermore, rinse can be performed along with water inflow for the sec...

[0091]Washing is performed at the water temperature of 30° C. and capacity of 60% by employing electrolyzed water and with standard course.

[0092]Group 5, during washing under water temperature of 39.0° C., tap water will be firstly electrolyzed in the electrolyzing cell in which alkaline ionized water and acidic ionized water with steady PH will be produced, the alkaline ionized water is introduced into the washing tub while the acidic ionized water will be stored. PH in the tub will be 10.103 after the addition of certain quantity of modifying agent. When the water level in the washing tub reaches a predetermined level, washing is performed with washing water level 6 and rinsing water level 10 and in standard course for twenty-five minutes, and the total washing period lasts for fifty-seven minutes. It can be measured that the surface tension of washing water is 30 mN / m, electrical conductivity is 57 us / cm and detergency ratio is 0.3631.

[0093]Group 6, Water temperature is 37.9° C. ...

Abstract

A washing machine which has no need of adding detergent by the user and the washing method thereof the said washing method comprises balancing setting the PH surface tension electrical conductivity and hardness of the washing liquid in a certain range, washing in general automatic washing machine with the use of a high PH electrolyzed water combined with a regulator; in which the PH of the said washing liquid is in the range of 8.5-1 I, the electrical conductivity of it is in the range of 261 us / cm-875 us / cm the surface tension is in the range of 2540 mN / m, the hardness is in the range of 5-400 ppm, if necessary 0.20.3 g / time of the regulator could be added in the above condition according to, the method of the invention it is possible to, realize washing without detergent; because the washing liquid is subjected to the treatment, the cost of the detergent will be saved and the pollution caused by detergents will be avoided, at the same time, the fabric hardening due to, it will be overcome, and an optimum washing condition will be obtained.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a washing condition for washing machine. More specifically, this invention relates to a washing method and a washing machine, through which the efficient detergency ratio can been ensured even without adding any detergent.DESCRIPTION OF THE PRIOR ART[0002]Presently, users have to add a large quantity of washing powder into their washing machines when washing the laundry. Nevertheless, washing powder left on the laundry may irritate the skin of human body. More than that, the non-degradable detergent contained in discharging water will cause environmental pollution.[0003]In recent years, washing machine that takes advantage of electrolyzed water for washing or sterilization and disinfection has come into being. In the circumstance of washing without detergent, users have to intensify the electrolytic efficiency to produce strong alkaline water with a relatively high PH so as to enhance washing efficiency. Unfortunately, the...
